Margin Notes appear as elegant cursive handwriting in the margins of player documents, written in a distinctive blue ink that seems to glow faintly under Bureau-issue lighting. The handwriting varies by author, creating a tapestry of different hands across a player's competitive history. Some notes are brief - a single word, a symbol, a question mark - while others fill entire margins with detailed behavioral observations. The notes accumulate over time, meaning more margin notes indicates more Bureau attention.

Margin Note serves as the Bureau's true opinion layer - a parallel tracking system that reveals what agents really think about players, which may differ significantly from their official clearance status. In a world where 'Trust No One' is the operative motto, the margin notes expose the hidden concerns, suspicions, and occasionally praises that exist outside the official narrative.
